Interactions of the artificial light sources and the window glazing of buildings

摘要

The article focuses on the issue of determining the real value of the heat transfer coefficient on the window glazing U_g in interaction of the window glazing and the artificial lighting. Measurements by the method of measuring the heat flow in situ conditions showed certain effects of the artificial lighting on the value U_g of the transparent constructions of a building. This knowledge can be used for energy performance evaluation of buildings.%W artykule podjęto probe określenia współczynnika transferu ciepła wynikającego z interakcji oszklenia i sztucznego oświetlenia. Współczynnik transferu ciepła zależy między innymi od konstrukcji budynku.
